re doing the valve cover that I have a Wagner adjustable PCV valve in.
The Wagner PCV valve itself is a nice part, but I thought the grommet that they supply with it does not really seal that valve the best around the base.
Found Dorman 42320 grommet that is a better fit to the Wagner PCV valve. It holds the PCV valve very securely.

just passing this on.
